The KMT39 is a magnetic field sensor based on the anisotropic magneto resistance effect, i.e. it is sensing the magnetic field direction independently on the magnetic field strength for applied field strengths H>25 kA/m. The sensor contains two parallel supplied Wheatstone bridges, which enclose a sensitive angle of 45 degrees. 
     With reduced accuracy, the sensor KMT39 may be used with a field strength of H0 ≥ 15 kA/m (at room temperature). Most magnets show a decreasing field strength with temperature while the magnetic field direction is unchanged.
